In the opening months of his tenure as manager two years ago, Brendan Rodgers took his squad to North America and Canada - playing friendly fixtures in Toronto, Boston and Baltimore.
Allen did not seal his switch from Swansea City until August of that year, however, and missed out on the chance to experience playing at Fenway Park and meeting fans from across North America.
But with the Reds set to return this pre-season - playing AS Roma in Boston and then competing in the Guinness International Champions Cup with games against Olympiacos, Manchester City and AC - the midfielder will finally get his chance.
"I'm really looking forward to it," the Welshman enthused to LFCtour.com. "In the summer I signed, I came just after the pre-season tour to America.
"I was a bit disappointed to have missed that but it's a good chance for me to go now. I spoke to the lads and everyone really enjoyed it. The support you get out there is pretty incredible and I'm certainly looking forward to experiencing it this summer.
"I have been to Florida as a kid; I have been to New York - Wales played a friendly there a few years ago - so I've had a couple of trips.
"We don't get too many opportunities to travel and play in these places so it's a great chance, if you're a supporter, to come and watch us live in action. I'm sure the fans will enjoy the experience."
Clashes with a heavyweight side from Italian football, giants from the Greek league and Barclays Premier League rivals City will provide Rodgers' men with tough obstacles Stateside - a challenge that Allen believes will be helpful in the build-up to the 2014-15 campaign.
The No.24 added: "You want to test yourself before the season starts. You want to make sure you're up to a high standard. There's no better way than to test yourself against those teams. That will be a great bonus."
Although he was not a member of the travelling party to America in 2012, Allen joined his teammates for the journey to Indonesia, Australia and Thailand last year where he experienced an unprecedented amount of support from the local fans who created a frenzied atmosphere everywhere the team went.
"People warned me that it's pretty impressive how much global support you get to see and witness, but to experience it first-hand blew me away really - it was incredible," claimed Allen.
"It's an experience I'll never forget. The amount of fans that turn out to watch you in pre-season games is something that I've never experienced before. The arrivals are the big one - getting off the plane and seeing the amount of fans that have come out to see you takes your breath away. It's incredible and hopefully this tour will be similar."
